Describes study of junior high school students in Israel that tested the effectiveness of microcomputer-based software designed to shape students' intuitions in the understanding of graphs of quantitative relationships. Retention and integration of microcomputer activities are discussed, and treatments for the experimental and control groups are…

Describes four activities for the French-as-a-Second-Language classroom, including: a lesson in the interpretation of graphs (Lescure); a unit on measurement, money systems, museums, and schools in France (Berteloot, Ploquin); oral and written exercises based on French history and culture (Ploquin, Store); and a vocabulary development activity…

Examines two databases--MEDLINE and ABI/INFORM--as currently implemented on laserdisk, commercial systems, and local time-sharing in the University of Pennsylvania libraries. The direct costs to the library of installing and operating the three formats are analyzed, and costs and benefits to users are discussed, including comparisons of the…

A survey of 123 users at the National Agricultural Library and Purdue University showed that, for most measures of acceptability, users preferred online or digital videodisc versions of the Pork Industry Handbook to the printed version. User characteristics were examined as factors that might influence responses. (Author/MES)

Presents a case study of how one 11th-grader learned the meaning of the velocity sign. Her learning was not just an acknowledgment of a rule but also a broad questioning and revision of her thinking about graphs and motion. (16 references) (Author/MKR)

Demonstrates how graphing calculators can be used by students to solve equations involving absolute value. Allows students to make connections between the algebraic and graphical representations of the problem. (MDH)

Discusses the use of graphing calculators by middle school students in an enrichment program for economically disadvantaged students and describes exercises to help students develop an understanding of variables and functions. (MKR)

Examines the process of consonant cluster reduction in the English of residents of a San Antonio, Texas, "barrio." The author compares Tejano patterns of "/-t,d/" deletion with the pan-English pattern. Results suggest a pattern of convergence and divergence. The study shows that Mexican American English exhibits regional and…

Multifaceted Rasch analysis was used to determine whether bias was evident in the way a group of raters graded two different versions of an oral interaction test, undertaken by the same candidates. Results indicate that certain raters consistently rated the tape version of the test more harshly while others rated the live one more harshly. (10…

Maintains that preparing graphs is an essential part of data analysis and representation. Asserts that, although psychologists use graphs extensively, most textbooks provide limited techniques for designing graphs. Reviews research on graphical techniques and includes recommended articles on the topic. (CFR)

Investigated the appropriateness of microcomputer-based laboratories (MBLs) for elementary school students. Reports that children expanded their repertoire of graph-making and interpreting skills and MBLs supported scientific inquiry for and by the children. (28 references) (Author/JRH)

Explores alternative strategies to solve algebraic equations that do not lend themselves to traditional methods. Examines one nontraditional equation by a graphical approach using a graphing utility and by a numerical approach using spreadsheets. Discusses new basic skills for algebra utilizing technology. Provides a computer program to solve…

Presents a collection of fall and Halloween activities for elementary students, including pumpkin poetry, batty bulletin boards (graphing), vegetable variety art, old time radio mysteries, paper doll Halloween safety, career dress-up day, imaginative Halloween writing, and matching animals with foods they eat. A student page offers a Dracula…

Presents results of a study examining how introductory economics students use graphic analysis. Concludes that the difficulties students have in analyzing an economic problem graphically result from problems with concept formation. Suggests that videotaping can assist instructors to understand and anticipate the learning processes that students…

Discussed are the possible uses of spreadsheets in the undergraduate curriculum in chemical engineering classes. The advantages and flexibility of spreadsheets, spreadsheet instruction, graphing capabilities, assignment examples, and conclusions are described. (KR)
